lie it known that l, CORNELIUS; Concoimn, a citizen of the Ql'uitetl States, l'CSlill in the borough ot Bronx, city ew York" in the eounty of New York 22ml State New York, have invented oei'tziin new and useful Ill'IIIHOVCDlOIItS in ll ypefi i riting Meiehines, of which the :lollmving is s specification.

This invention relates to the letter nieohzinisn'i of iypowi'iting machine 'ilho principal object of the present invention is to proviele improved inc-ens toe sl ing the paper ezei'i'ingye reaction of :3 letter space, and maintaining the carriage in this relative position so as to enable the typist to close spans the letters when sequined.

In carrying out this invention 1 mount the rocker of the merit mechanism upon a shi'ltshle Clllllel or support and an extra key is pi'ovitletl on the hevbomil for moving this earlier.

the rocker 6. The latter cerrles we Ieed clog 7 engaging the escepement Wheel 8 connected to pinion 9 meshing with the feed melt 10 of the carriage 11. All of these paths are found in the usual form of Under WOOljl Writing machine.

To shift the carriage a fraction ofa letter specie to the right, 1 mount upon the keyboard an additional key 1.2 upon a keybar I whieh may be pivotetl to the common fuler'ann hm. of the rest of the keys. A link 14: connects this key be! to a lever 15 fulerurned upon it bracket 16 fixed to the frame 17 which omrries the eseepement mechanism 'lh lever 15 has a com slot into Which projects e pin 18 mounted upon a slide or can iGl 1!} to which the rocker 6 is pivoted, so *hat the movement of the lever 15 Will positively operate the carrier 19 and positively holcl said. carrier against movement in either 'on from any position to Which it is u: no

Lineet: bronp'ht by the 0am lever. When the key 12 1s d n'essetl, the rocker 1s shifted through the above connection from its normal position shown in Fig. :2 to the positlon shown in. Fig. 3, thus giving the oscapement wheel a partial turn, which, through the pinion :n'ml feed rack, shifts the carriage a fraction of a letter space to the right against the action of the iinpelling spring. So long as the lcey l2 kept in depressed or partially de- -n'essed position theoumiege Will be main teined in a eorresponilingly shifted position,

during which time a Word may be Written which will be shl. t: l a, fraction of an letter space to the left. 1 preferably so proportion the parts that when the key is fully clepiessecl the carriage will be shifted one half of letter space to the right, so that When a Word is inserted, containing one more letter, to take the place of a word which has vbeen. ereseol, on equal space will be left on each side of the inserted word.

The earlier 19 preferably comprises two 20 and 21 carrying the pivots 22 upon which the roeker is mounted, one ofsziitl pivots being; threaded for adjustment of the rocker relatively to the carrier; The b-loe .s are connected by a yoke which is olfset to one side of the blocks to allow the piv-' otal n'iovelnen't of the rocke These blocks slide in guides 21 and 25 which are fastened.
